Product details

outdoor AC boundary vacuum load switch

 FZW28-12F ( FFK ) type user dividing vacuum load switch ( referred to as the demarcation switch ) used in outdoor column installed occasions, has manual and electric operation function. The switch body is introduced by Toshiba Co of Japan VSP5-12 technology ,the switch is a maintenance-free load switch . Vacuum interrupter and SF6 gas on ground and inter phase insulating medium.

 This product conforms to GB3804 AC high voltage load switch: " GBT11022 " and " high voltage switchgear and control gear standards common technical requirements " .

 FZW28-12F type dividing vacuum load switch ( FZW28-12 switch and FDR-01 controller ) with fault detection function, protection and control functions and communication functions, installed in the 10kV overhead transmission line, can realize the automatic removal of single-phase grounding fault and automatic isolation of inter phase short circuit fault . Mounting points for 10kV distribution line user line responsibility demarcation point, also can be applied to meet the requirements of the branch line junction.
